5.7.3 Host Port Routing
The "Host Network" is the equivalent of the IP route command.
Field AT Command Description
Primary
Gateway
Your device is the Primary Gateway for the network behind
a router connected to it and ALEOS responds to ARPs for
all non-host Ethernet subnets.
Host Network 2
and Host
Network 3
Network to route to host IF.
Host Network 2 and 3 are secondary networks connected
to the RLXIC-EV. For example, 192.168.10.0.
Host Network
Subnet Mask 2
and Host
Network Subnet
Mask 3
This is the subnet for the applicable network. For example,
255.255.255.0, which would with the setting above define a
secondary network of 192.168.10.0/24.
Host Network 2
Route and Host
Network 3 Route
This indicates what type of router is being used for the host
network. If it is a traditional router, which handles ARP for
addresses on its subnet, select Ethernet. If it is a "dumb"
gateway, which is a conduit to a subnet but does not
handle any ARP, select Gateway.
When Gateway is selected, ALEOS will ARP for the
destination address and send it to the defined Host
Network Gateway address.
Host Network 2
Gateway and
Host Network 3
Gateway
This is the IP address of the 'dumb' Gateway. This should
be left as 0.0.0.0 if the Host Network Route is Ethernet.
Many routers will respond to ARP requests for subnets
behind the router. The default is Ethernet, which means
the user does not have to configure the gateway IP.
However, some routers do not respond to ARP requests
for subnets. Hence, users need to enter the gateway
address.
